Abstract

Un mode de réalisation concerne un système d’injection, comprenant un corps de seringue définissant une chambre de médicament interne; un élément bouchon conçu pour être inséré à l’intérieur de la chambre de médicament pour maintenir le médicament à l’intérieur de la chambre de médicament; un élément piston conçu pour être manipulé manuellement afin d’insérer l’élément bouchon par rapport au corps de seringue; une aiguille ayant une extrémité proximale et une extrémité distale, l’extrémité proximale comprenant une géométrie d’ancrage conçue pour au moins partiellement pénétrer dans l’élément bouchon de telle sorte qu’après retrait de l’élément bouchon, l’aiguille est tirée en direction proximale avec le bouchon pour être au moins partiellement contenue à l’intérieur de la chambre de médicament; et un élément de stockage d’énergie couplé de façon opérationnelle entre l’élément bouchon et le corps de seringue, l’élément de stockage d’énergie étant conçu pour faciliter le retrait de l’élément bouchon par rapport au corps de seringue.
